BN530A Oxidized Polyethylene Wax: Precisely Solve Three Core Challenges in PVC Extrusion

In PVC extrusion production, material scorching, severe equipment wear and poor pigment dispersion are three common pain points troubling many manufacturers. These issues not only impair the appearance and quality of finished products and reduce production efficiency, but also raise equipment maintenance costs, cause raw material losses and restrict production profitability.

BN530A high-performance oxidized polyethylene wax lubricant is developed for a wide range of PVC extrusion processes. Featuring low dosage, high compatibility and multi-functional performance, it addresses industry challenges in one solution and suits the manufacturing of products across multiple sectors.

1. Product Overview

BN530A is a high-density oxidized polyethylene wax with excellent compatibility, perfectly matching various PVC extrusion processes. It requires only a low dosage of 0.05–0.3 phr to form a uniform and stable lubricating layer within the material system. It delivers lubrication, plasticization, mold release and dispersion functions simultaneously. It eliminates processing defects, improves surface properties of finished parts, protects processing equipment, boosts production efficiency and color quality, and offers outstanding overall cost performance.

2. Targeted Industry Pain Points | Three Core Advantages to Resolve Processing Issues

01 Eliminate Material Scorching and Surface Defects

❓ Industry challenge: During PVC extrusion, melt slippage and viscous flow easily trigger material scorching and coking, resulting in pits, scratches and blemishes on finished products, which directly lead to rejected parts.

Solution: BN530A provides superior synergistic lubrication. It efficiently builds a uniform, stable lubricating isolation layer between PVC melt and mold inner walls. It optimizes melt flow behavior, prevents scorching and coking caused by viscosity variation and melt slippage, eliminates surface defects at the source and greatly raises finished product yield.

02 Stabilize Plasticization and Greatly Reduce Equipment Wear

❓ Industry challenge: Uneven PVC plasticization and unstable extruder feeding are primary causes of excessive wear on screws and barrels. This increases maintenance expenses, shortens equipment service life and disrupts continuous production.

Solution: BN530A enables uniform, controllable and stable plasticization. It optimizes material flow and feeding status to achieve full and steady feeding into the extruder. It effectively cuts friction and wear on screws and barrels, extends equipment service life and markedly improves extrusion efficiency to help manufacturers reduce costs and increase profits.

In addition, it improves metal release performance of the compound, preventing material adhesion to equipment surfaces and further optimizing processing conditions.

03 Enhance Pigment Dispersion and Upgrade Color Quality of Finished Goods

❓ Industry challenge: Poor dispersion of pigments and fillers causes color spots, white specks and inconsistent shading, leading to dull color and poor texture, which weakens product market competitiveness.

Solution: BN530A significantly improves homogenization and dispersion of PVC melt, enabling full and even distribution of pigments and fillers in the PVC matrix. It avoids uneven coloration and color difference, improves color strength and color uniformity, and enhances surface gloss and overall texture of finished products.

3. Wide Application Scope

Thanks to its excellent processability and versatility, BN530A is widely used in polymer processing fields:

· Flexible & rigid PVC products (pipes, profiles, sheets, etc.)

· PVC foamed products

· PVC color masterbatch

· Powder coatings

· Asphalt modification
